darker in sub-terminal space, all the lines narrow, very indistinct and 

 paler. Basal half-line faint ; median space lighter shaded ; median 

 lines more distinctly marked at costa, the transverse anterior angulated 

 at median vein thence straight to internal margin, transverse posterior 

 arcuated at the disc, the point of reflection approximate to the lower 

 outer corner of the squarish dark colored reniform spot; sub-terminal 

 line dark, marked at costa, interrupted, indistinct. Posterior wings 

 with a very broad terminal black band, straightly margined inwardly ; 

 a very narrow pale yellow median band, constricted greatly in the mid- 

 dle by the large lunate discal spot, which is absorbed inwardly by the 

 black color of the base so as not to be readily separated from it; fringes 

 whitish with a distinct cinereous line. Thorax and head colored as 

 anterior wings, abdomen paler, sprinkled with reddish underneath, as 

 are also the legs on the outside. Under surface of anterior wings pale 

 yellow, with a large basal, and rounded discal, black spots; terminal 

 band black, very wide, tapering to costa, leaving the apex and apical 

 terminal margin ochraceous; costa with reddish scales. Under surface 

 of posterior wings yellowish, the broad terminal black band is continued 

 a little over half the width of the wing from anal angle; costa, and termi- 

 nal margin below the apex, sprinkled with reddish scales; base with a 

 black spot more or less divided by yellowish scales, widely separated from 

 costal margin ; internal margin marked with blackish. 9 9 Exp. 1.10

Larger and sufficiently distinct from A. li/nx^ of our Eastern and 

 Middle States, which it somewhat resembles. 



I name this fine species after Mr. A. S. Packard, Jr., whose ento- 

 mological writings I very greatly appreciate. 



Anthoecia nobilis, nov. sp. (Plate 6, fig. 3. 9 •) 



Very much resembling A. Packardii; the coloration of the anterior 

 wings is difiierent, the basal and sub-terminal spaces being strongly 

 tinged with reddish; the median lines are distinct, white; the transverse 

 anterior more undulate ; the median yellow band of the posterior wings 

 is slightly broader. The thorax shares the reddish tinge of the basal 

 and sub-terminal spaces on anterior wings. Notwithstanding these 

 differences, it has much the same general appearance, and I look for
